Siemens Industrial Controls 3RA2934-2B Interlock 322838-752 this non-fused component simplifies maintenanceThe Siemens 3RA2934 2B mechanical interlock is a critical safety component for field assembled reversing contactor combinations. Designed to integrate seamlessly within the SIRIUS modular system, this side mount unit provides a physical lockout between two power contactors. It serves as a secondary failsafe, ensuring that both contactors cannot be engaged simultaneously, which prevents catastrophic phase to phase short circuits in motor control
